For the Cake

  • Rolled Oats: Use old-fashioned rolled oats for the best chewy texture. They provide fantastic structure and a boost of fiber.
  • Whole Wheat Flour: This adds a nutty flavor and more nutrients compared to all-purpose flour.
  • Apples: We recommend crisp, sweet-tart apples like Honeycrisp, Gala, or Braeburn. They hold their shape well and provide the perfect apple flavor.
  • Unsweetened Applesauce: A key ingredient for moisture and natural sweetness, allowing us to reduce the oil.
  • Greek Yogurt: Adds protein and even more moisture, resulting in a tender, rich crumb.
  • Maple Syrup: Our preferred natural sweetener. Honey also works well as a substitute.
  • Eggs: They bind the ingredients together and provide structure.
  • Coconut Oil: Just a touch of melted coconut oil for richness.
  • Spices: A warm blend of cinnamon, nutmeg, and allspice gives this cake its classic, cozy flavor.
  • Leavening: Baking powder and baking soda help the cake rise beautifully.

For the Streusel Topping (Optional)

For an extra touch of texture and sweetness, a simple streusel topping is highly recommended. It creates a delightful crunch that contrasts perfectly with the soft cake.

  • Rolled Oats & Whole Wheat Flour: The base of our crunchy topping.
  • Coconut Sugar: Adds a lovely caramelized sweetness.
  • Cinnamon: For that essential warm spice flavor.
  • Melted Coconut Oil: Binds the streusel together and helps it get golden and crispy in the oven.

Step-by-Step Instructions

Making this Healthy Oatmeal Apple Cake is as easy as mix, pour, and bake. Follow these simple steps for a perfect result every time.

Step 1: Preparation

First, preheat your oven to 350°F (175°C). Lightly grease and flour an 8×8 inch baking pan. This prevents the cake from sticking and ensures clean slices later. In a small bowl, prepare the streusel topping by combining the oats, flour, coconut sugar, and cinnamon. Drizzle in the melted coconut oil and mix with a fork until crumbly. Set aside.

Step 2: Mix the Batter

In a large bowl, whisk together the dry ingredients: rolled oats, whole wheat flour, baking powder, baking soda, cinnamon, nutmeg, allspice, and salt. In a separate medium bowl, whisk the wet ingredients: unsweetened applesauce, Greek yogurt, maple syrup, eggs, and melted coconut oil. Pour the wet ingredients into the dry ingredients and stir gently until just combined. Be careful not to overmix! Finally, fold in the diced apples.

Step 3: Assemble and Bake

Pour the batter into your prepared baking pan and spread it into an even layer. Sprinkle the prepared streusel topping evenly over the batter. Bake for 35-45 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for at least 20 minutes before slicing and serving. This helps it set properly.

Baker’s Tips for the Perfect Healthy Oatmeal Apple Cake

Want to ensure your cake is absolutely flawless? Here are a few expert tips from our kitchen to yours.

  • Don’t Overmix the Batter: Overmixing can develop the gluten in the flour, resulting in a tough cake. Stir until the ingredients are just combined for a tender crumb.
  • Dice Apples Uniformly: Cut your apples into small, uniform pieces (about 1/2 inch) to ensure they cook through evenly and are distributed well in every slice.
  • Check for Doneness Correctly: Ovens can vary. Start checking the cake at the 35-minute mark. The cake is done when a toothpick comes out with a few moist crumbs attached, but no wet batter.
  • Let It Cool: We know it’s tempting to dive right in, but allowing the cake to cool is crucial. It finishes cooking from the residual heat and firms up, making it much easier to slice. For another amazing dessert, try this Easy Peach Cake Recipe.

Delicious Variations to Try

This Healthy Oatmeal Apple Cake is fantastic as is, but it’s also a wonderful base for your own creative twists. Here are a few ideas to get you started.

  • Add Nuts or Seeds: For extra crunch and healthy fats, fold 1/2 cup of chopped walnuts, pecans, or pumpkin seeds into the batter.
  • Include Dried Fruit: Add 1/2 cup of raisins, dried cranberries, or chopped dates for chewy bursts of sweetness.
  • Make it a Loaf: You can bake this recipe in a 9×5 inch loaf pan. Just be sure to monitor the baking time, as it may need a bit longer.
  • Chocolate Chip Surprise: For a more indulgent treat, fold in 1/2 cup of dark chocolate chips. The combination of apple and chocolate is surprisingly delicious. If you love chocolate, you must check out these 3-Ingredient Banana Brownies.

Storing Your Oatmeal Apple Cake

This cake stores beautifully, making it perfect for meal prep. To store, allow the cake to cool completely. Cover the pan tightly with plastic wrap or transfer slices to an airtight container. It will stay fresh at room temperature for up to 3 days or in the refrigerator for up to a week. For longer storage, you can freeze individual slices for up to 3 months.

Frequently Asked Questions

Yes, you can! To make this cake gluten-free, simply substitute the whole wheat flour with a 1:1 gluten-free baking flour blend and use certified gluten-free rolled oats.

To make it dairy-free, you can use a plant-based yogurt (like coconut or almond) and ensure you are using coconut oil. To make it vegan, you would also need to substitute the eggs with a vegan egg replacer, such as flax eggs.

We don’t recommend substituting the oats. Rolled oats provide the best texture for this cake. Steel-cut oats are too tough and won’t soften enough, while quick oats can become mushy and alter the cake’s structure.

Store the cake in an airtight container at room temperature for up to 3 days or in the refrigerator for up to a week. It also freezes well for up to 3 months.

We recommend using a firm, crisp apple that holds its shape during baking. Varieties like Honeycrisp, Gala, Braeburn, or Granny Smith (for a more tart flavor) work wonderfully in this recipe.
